Precautionary/preparedness actions...

High wave action makes swimming difficult and can tire even astrong swimmer quickly.

Structural currents form along piers where longshore currents andwave action flow into the structure. Structural currents cansweep you out into deeper water along the pier structure.

A longshore current is a lake current that moves parallel toshore. Longshore currents can be strong enough to preventswimmers from being able to keep their feet on the bottom... making it difficult to return to shore.
